我最近购买了一台新台式机并购买了 USB 无线适配器以便使用无线互联网。我决定选择这个型号因为过去我的大多数无线卡都因专有驱动程序而出现问题。很高兴拥有“开箱即用”的互联网，但我尚未成功使其正常工作
我浏览了互联网一段时间并尝试了以下选项，但也没有成功。
- 安装的固件-atheros
- 尝试将适配器插入不同的 USB 插槽（你永远不知道......）
今天早上点燃一支蜡烛......

从文档中：适用于 GNU / Linux 的 Penguin 无线 N USB 适配器 (TPE-N150USB) Debian 固件安装
要将 Debian 7 (Wheezy) 或 Debian 8 (Jessie) 或 Debian 9 (Stretch) 与适配器一起使用，请执行以下操作： 您不需要升级内核，只需将固件复制到您的
/lib/firmware
作为根用户：
cd /lib/firmware
wget https://www.thinkpenguin.com/files/ath9k_firmware_free-version/htc_9271.fw
wget https://www.thinkpenguin.com/files/ath9k_firmware_free-version/htc_7010.fw
reboot
另请注意：如果您使用 Debian 9 (Stretch) 并且看到接入点列表，但无法连接，请尝试以下操作：
sudo nano /etc/NetworkManager/NetworkManager.conf
添加以下行：
[device]
wifi.scan-rand-mac-address=0
然后重新启动网络管理器：
sudo service network-manager restart
